How to assign different colors to different labels?

Hi,

I saw in one paper that they are showing their segmentation results of different objects with different colors and overlayed on the input image. As you can see in the following image.

Could I ask how we can assign different colors to different labels obtained from a segmentation algorithms with different objects? I would like to do the same on the segmentation results that I am obtaining from my algorithm. I have 0 as background and labels 1-to-4 as 4 different objects. Your help is really appreciated.

Thanks

See this snippet:

% Label each blob with 8-connectivity, so we can make measurements of it
[labeledImage, numberOfBlobs] = bwlabel(binaryImage, 8);
% Apply a variety of pseudo-colors to the regions.
coloredLabelsImage = label2rgb (labeledImage, 'hsv', 'k', 'shuffle'); 
% Display the pseudo-colored image.
imshow(coloredLabelsImage);
